The format is the main difference
Lingopie is a curated language-learning streaming library built around TV shows and movies, with interactive subtitles, click-to-save flashcards, and level grading. FluentU is also a curated-video platform, but organizes the experience around shorter and YouTube-style clips with interactive subtitles and quizzes.
The choice therefore begins with the session format. A learner who wants an episodic viewing routine may prefer Lingopie; a learner who wants shorter video lessons and a quiz-centered format may prefer FluentU.
Price comparison
Lingopie currently lists annual promotional pricing from ~$6.99 per month; its 3-month plan is $13.99 per month for one language, while the annual and lifetime offers cover all languages. Its pricing is promotion-driven, so the current checkout page is the correct final reference.
FluentU's figures should stay approximate: ~ $30 per month monthly, or ~ $12–20 per month on annual plans during sales. The two platforms are not priced in the same way, so compare the actual current checkout terms rather than treating a promotional annual equivalent as a fixed monthly price.
Language coverage and trials
Lingopie offers 15 languages. FluentU lists ~9–10 languages, with all included. That makes Lingopie the broader of the two by the supplied language count, while the content format remains the more important difference for most buyers.
Lingopie offers a 7-day free trial; see the yearly-refund catch before treating that trial as a no-questions-asked experiment. FluentU's trial is approximately 14 days. Both claims should be checked against the live checkout terms because subscription policies can change.
Who should choose which
Choose Lingopie if a curated TV-and-movie library and binge-format immersion are the motivation. Choose FluentU if short clips, interactive subtitles, and quizzes make a more structured study session appealing. Neither is the same thing as an extension used directly on a personal streaming account.
